Natural Habitat

Found in woodlands, tall grass, and meadows; occasionally enters human structures like gardens or garages.

Diet & Feeding

Active predator that eats various insects and other spiders. They hunt by roaming and pouncing rather than using webs for capture.

Behavior Patterns

Females carry their egg sacs in their chelicerae and pedipalps. Before the eggs hatch, the mother builds a silk 'nursery web' to protect the spiderlings. They are mostly nocturnal hunters.

Risks & Benefits

Benefits the ecosystem by controlling insect populations. They are not medically significant to humans; their bite is rare and typically no more painful than a bee sting unless an individual has an allergy.
